    Resurrecting this post from the dead and first time poster!

    Arne K which positions did you install the NJM2060 & OPA4227 for the the line - level?

    Also looking for the switch for the impedance selector in the back of the unit for the phono input.
    Anyone here looking to part with one or know a source where one can be obtained?

    Regards,
    Rudy.
